Sort Even and Odd (Easy-4) gives second graders a fresh batch of two-digit numbers to classify: 7, 22, 31, 16, 3, and 28 each land in the Even or Odd column. The fill-in section asks whether 30 is even, names the next odd number after 17, and works through a sharing problem where 6 apples are split between two friends.

Four true-or-false statements about 10, 19, and 24 reinforce the rule that the ones digit decides everything, helping children read any number at a glance and know its parity instantly.
